Miguel has personality points and interests, something not every ancestral Sim has. He is completely resurrectable, even though he doesn't have a grave. Miguel has the Romanceaspiration, and the Scorpiozodiac sign. As far as personality, he is very active, somewhat neat, and a little bit outgoing. But he is very grouchy and serious.

According to Miguel's SimDNA in SimPE, his hair was black before it turned grey. According to his age data, he had 15 days left in the elderlife stage when he died. Miguel's facial structure is seemingly identical to the 4th Maxis face template in Create a Sim. While all the memories of pre-made playable Sims in Riverblossom Hills are positive, he has negative memories of his wife and daughter's deaths.
